Analysis of effect by ascorbic acid on preparation of gold nanoparticles by the method of gold-deposition development

从反应机理和应用两方面对金沉积发育方法进行了研究。在银盐感光材料的暴露区域上形成的光石银团簇可作为制备金纳米粒子的催化剂。抗坏血酸的加入使反应速率显著提高，并从温度依赖性等方面分析了反应机理。将该方法制备的精细摄影图像应用于辐射径迹分析和金层照片制备，在径迹能量损失分析或图像长期保存方面取得了丰硕的成果。

Gold-deposition development method was investigated from both points of the reaction mechanism and its application. Photolitic silver clusters formed on the exposed area of silver-salt photographic materials act as a catalyst to prepare gold nanoparticles. Drastic increase in reaction rate was obtained by the addition of ascorbic acid and the reaction mechanism was analyzed from the temperature dependence, etc. The fine photographic images prepared by this method were applied to the analysis of radiation tracks and preparation of gold-layer photographs, which produced fruitful results of the analysis of energy loss of the tracks or long-term image preservation.
